My refutable hypothesis is that we would find increased support from Republicans, greatly increased support from Democrats, but insufficient improvements in understanding to explain these changes.
An economical, currently not easily refutable hypothesis, for which there is at present only indicative evidence, is suggested by a recent finding (Zhang et al., 2010).
We provide the first head-to-head test of rival explanations of these behavioral patterns by developing refutable hypotheses for the strategic behavior, yea-saying, anchoring, and cost-expectations models.
Do the authors imply that by refuting some dozens (or hundreds, or thousands) of clades, all remaining un-refuted ones (or the refutable ones among them) are increased in status?
We can think of these refutable subhypotheses as different ways in which the main hypothesis may be true.
For example, the theorem mentioned establishes a connection between falsifiability and testability, but one that is more attenuated than the naïve Popperian envisions: it is not necessary that the hypotheses under test be directly falsifiable; rather, there must be ways of strengthening each hypothesis that yield a countable number of refutable "subhypotheses".
What Wittgenstein says, however, is that the modalities provable and refutable are shadowy forms of reality that possibility is not actuality in mathematics [ PR §§141, 144, 172), (PG 281, 283, 299, 371, 466, 469)], (LFM 139)].
This theory not only is refutable, it makes strong empirical predictions.
"A theory which is not refutable by any conceivable event is non-scientific.
As formulated by Popper (1963), " A theory which is not refutable by any conceivable event is non-scientific.
For Popper, a theory is scientific only if it is refutable by a conceivable event.
